Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Completely free, open-source, self-hosted with no licensing fees
GraphQL API and admin UI generated automatically from schema
Strong TypeScript support and Prisma-based migrations
Fine-grained, code-defined access control
Backed by an experienced consultancy (Thinkmill) with enterprise delivery history
Cons
No official managed hosting offering from the Keystone project
Requires Node.js and database operational expertise to self-host
Smaller ecosystem and plugin marketplace than Strapi or WordPress
GraphQL-first design has a learning curve for teams used to REST
Migration from older Keystone (v5/Express/MongoDB) versions requires significant rework
Ech0
Pros
Completely free and open source with no ads, tracking, or subscription fees
Very lightweight, able to run on low-power hardware like a Raspberry Pi
Unusually rich feature set for a small project, including MCP and AI-powered features
Supports ActivityPub federation, avoiding lock-in to a single platform
Cons
No official hosted or managed cloud version; requires self-hosting
Maintained primarily by a single developer, which carries bus-factor risk
AGPL-3.0 licensing requires source disclosure for modified public deployments
Documentation and community support skew toward a Chinese-speaking audience
